CH641684A5 - DEVICE FOR FIXING A SHOE ON A SOLE, PARTICULARLY FOR FIXING A SKI. - Google Patents

Description

The present invention aims to remedy these drawbacks and is characterized in that it comprises two independent stirrups, each made in a single piece, articulated on a rigid sole and passing under this sole, along a cylindrical axis in grooves transverse, of corresponding shape, the lateral edges of the sole being raised so as to go up along the foot, the two stirrups respectively cooperating with a front support assembly and a rear support assembly arranged on each side of the sole.

The invention has the advantage that it makes it possible to maintain the foot and the leg on a ski by means of existing safety bindings.

In addition, the foot is fitted with a waterproof and arbitrary flexible shoe. This support device makes it possible to practice alpine skiing as well as cross-country skiing, or even ski walking.

The present invention will be better understood using the schematic embodiments shown, by way of nonlimiting example, in the attached drawings, in which:

fig. 1 is a side view of the entire device on a reduced scale,

fig. 2 is a section along AB of FIG. 1 in the upper part, according to CD in fig. 1 in the lower part,

fig. 3 is a section through a detail of the sole and of one of the stirrups, associated with the annular wedge provided with bulges,

fig. 4 is a side view of the foot and leg support system.

According to fig. 1, the device comprises a sole 1 whose lateral edges 2 are raised. The lower part of the stirrups 4 is positioned in one of the transverse grooves 3. The annular wedges, bulge rings 5, distance the raised edges 2 of the sole from the internal faces of the stirrups 7, exerting pressure on the foot in his shoe flexible, in the front and rear part thereof. The upper part of the stirrups 7 allows a height adjustment of the semi-rigid members 8 and 9 which maintain flexible pockets loaded with fluid (according to model 10). The external semi-rigid member, the widest of the three, appears at 11 and part of the height adjustment device at 12 '(locking eccentric according to model).

According to fig. 2, the device comprises a semi-rigid member 8 notched on the two faces of its side walls, retained between an internal semi-rigid member 9 notched on the outer face of its side walls and a semi-rigid external member 11 notched on the internal face of its side walls.

The semi-rigid member 11 is pierced with a hole 12 in the upper part: section AB, and a hole 13 in the lower part: section CD.

The semi-rigid member 9 is pierced with a hole in the upper part

14.

The semi-rigid member 8 comprises a peduncle 12 ′, section AB, embedded in an elastic piece 17, section AB, secured to a height adjustment member 18 blocked by the locking eccentric 12 ′ (depending on model), section AB, on the upper part of the stirrup 7: front section, section AB. The flexible pockets containing a fluid 10 distribute the pressures, cuts AB and CD.

According to fig. 3, scale 1, the lower part of the stirrup 4, located in the groove 3 of the sole 1, maintains the stirrup in position while the shim with variable thickness immobilized around the lateral upright of the stirrup 19 maintains spacing wanted the lateral edge of the sole 2 which presses on the shoe 6.

The operation is carried out as follows: after adjusting the height 12 ′ and adjusting the width using the shims 5, the foot is introduced into the open device. The closure of the device causes the semi-rigid member 8 to engage between the semi-rigid member 9 and the semi-rigid member 11. The introduction of the ski pole simultaneously into the aligned holes 14 of the member semi-rigid internal 9 and 13 of the semi-rigid external member 11, located some distance below the hole 14 and the front-rear, rear-front reciprocating lever movement, exerted by the stick, driven by the inter5

medial of the notches of the external semi-rigid organs and means an advance of the semi-rigid medium organ towards the internal semi-rigid organ. The pockets 10 distribute the pressures on the ankles and instep up to suitable pressure. The elastic assembly 16 and 17, associated with the clearance allowed by the fluid shims, allows front-rear flexibility.

The device is opened by introducing the tip of the ski pole into the hole 12 of the external semi-rigid member and by pushing backwards, causing the external semi-rigid member to tilt, that -this rotating around its lower rear angle io escapes its notches and tends to drive the semi-rigid intermediate member before. Associated with a pressure of the foot forward, this movement of the stick causes the opening of the device.

According to fig. 4, the particular embodiment of the system 20 comprises two front and rear stirrups 7 passing under a sole 1 15 and cooperating with a front support assembly 8, 10 and a rear support assembly 9,10 cooperating with each other and each side of the ankle.

The sole 1 is further provided with rising lateral edges 21

20

to ensure better support for the user's foot.

The front support assembly 8, 10 comprises an element 8 in the general shape of a horseshoe provided with a peduncle 22 resting on an elastic piece of rubber 23.

The peduncle 22 and the elastic piece are housed in a box 25 notched on its outer lateral edges. The peduncle 22 and the elastic piece 23 are held in the box by means of the lateral pins not shown in this figure of the peduncle 22.

The box 24, notched laterally, cooperates with the notches 25

formed on the internal face of an orifice of the front stirrup 7. This notch allows the height adjustment of the element 8 and of the part 10.

The horseshoe-shaped element 8 is provided on its sides with orifices 26 facing each other (a single orifice is visible in this figure). The first orifice 26 allows the passage of the cable for fixing the assembly formed by the front and rear stirrups 7 and the front support assemblies 8,10 and rear 9,10. The second orifice 26 receives the axis 27 of a locking piece 28.

When the system is blocked on the user's foot, the various parts forming the front and rear supports are tightened on the user's leg and are secured using a cable, the free end of which is connected to the locking part 28.

The user performs the tightening and locking of the system at his convenience by rotating the locking piece 28 around its axis 27 engaged in the orifice 26.

The locking part, according to this particular embodiment, comprises a ribbed lever, the ribs not visible in this figure bearing on a lateral bearing surface of the horseshoe-shaped element 8.

The front support element 10 has on its lateral faces a cam track 29 of curved shape. The horseshoe-shaped element 8 maintains the support element 10 by this cam path during the bending movements of the leg. In addition, the cam track 29 exerts a downward and rearward thrust when the system 20 is blocked to wedge the heel of the user.

The rear support piece 9 slides on the rear stirrup 7 and can be positioned at an adjustable height by means of notches formed on the internal faces of the part 9 cooperating with the notches 30 formed on the external face of the stirrup 7 .
